| 摘 要： | 翼身结合处的整流在民机气动中有很重要的作用,需要设计合适的外形以调整机翼上表面的压力分布及翼身结合处的气流,达到提高大型民用客机翼身组合体气动性能的目的.基于CATIA的自由曲面修形技术,采用自由曲线B样条的参数化方法,综合考虑工程约束(起落架布局),对民机构型翼身结合处进行了整流设计,并采用求解N-S方程的方法计算样...

| Abstract: | The wing-body fairing is very important in the civil aircraft configuration design.To improve the aerodynamic performances,it's necessary to design appropriate shape to adjust the pressure distribution on the upper surface of the wing and the turbulence flow at the wing body junction.Based on specific engineering requirements related to wing body fairing design,a free form parametric modeling method based on B-spline is proposed and implemented within CATIA;to improve the efficiency of the complete optimiza... |
